Kaimanawa mystery ancient wall - New Zealand

Near Lake Taupo in New Zealand is an enigmatic wall called the
Kaimanawa wall (https://bit.ly/3SsK2wZ). It faces north and consists
of smooth, megalithic stone blocks with symmetrical corners. The
blocks form perfectly together and are completely flat at the end.
They also go upwards and backwards in blocks and levels. Many
hypotheses flourish concerning the origins of its stone blocks, in
particular, whether the structure is man-made or a unique natural
formation.
The controversial wall became a topic for debate in the early 1990s
with Barry Brailsford’s publication of an article in the New Zealand
Listener called (https://bit.ly/3LE0QyL) "Megalith Mystery: Are
giant stones in the Kaimanawa Forest Park evidence of an ancient
New Zealand culture?". According to the article, the stone wall is
at least 2000 years old and was created by the first settlers of New
Zealand, the Waitaha, who were subsequently nearly exterminated
by the Maoris, who arrived only 800 years ago. (Or perhaps by people
who were here before the Waitaha).  Furthermore, Brailsford maintains
that the wall could link New Zealand with Egypt, South America, and
other ancient civilisations.  He lists twelve pieces of evidence for
its construction, for example, the fact that the visible stones in the
front are a uniform 1.9 metres wide by 1.6 metres tall, and one metre
wide (deep). 
However, politically, the view that civilizations existed in New
Zealand before the Maori culture is not very popular with the local
Maori people, the Department of Conservation archaeologists and
geologists and to just about every political party in New Zealand,
and the media attention following the publication of the article led
to a complete ban on the area. 
New Zealand archaeologists and anthropologists, naturally enough,
were not anxious to drastically revise their fundamental paradigm
assigning the discovery and colonization of New Zealand to the
Maori and ordered an investigation to be carried out on the rocks.
The conclusion made by the commissioned Geologists was that the
wall is an outcrop of a large ignimbrite, a natural formation,
created about 330,000 years ago. They claim that the block shapes
were produced by fractures in the rock when the hot ignimbrite
cooled. Displacement of the rocks may also be attributed to
earthquakes, volcanic eruptions, and other natural events.
The official line is that the Kaimanawa wall has been proclaimed
a "natural rock formation". But sceptics remain unpersuaded and
many believe that archaeologists and political figures are biased
in their investigations and not willing to revise old paradigms.
A convincing explanation supported by evidence-based proof on
either side of the argument has yet to be seen, but the controversy
surrounding the Kaimanawa wall does raise important questions
about how willing people really are to investigate the true origins
of man and its early civilizations.
